Understanding What Your Check Engine Light Means
Your check engine light can turn on for dozens of reasons—some simple, others more serious. It could be something as small as a loose gas cap or as complex as a misfiring cylinder or faulty oxygen sensor. The longer it’s ignored, the greater the risk of damage to key components like your catalytic converter. That’s why we encourage drivers to come in right away when that warning light appears. At Cornerstone Automotive, we’ll run a complete diagnostic scan and walk you through the findings in clear, straightforward terms.
Advanced Technology for Precise Testing
Our diagnostic equipment is the same kind used by dealership service departments, capable of reading manufacturer-specific codes for all makes and models. We analyze data from your car’s onboard computer and perform live tests to monitor fuel trim, emissions, ignition timing, and more. This allows us to catch hidden problems that generic code readers might miss. We combine that technology with old-fashioned mechanical know-how to give you the most accurate answers possible.
Preventing Costly Repairs Through Early Detection
A professional diagnostic test doesn’t just solve problems—it helps prevent them. By identifying potential issues early, you can often avoid major breakdowns and expensive repairs later. Whether it’s a faulty sensor, low voltage, or an intermittent electrical issue, catching it early keeps your vehicle running smoother and more efficiently. Think of diagnostics as a health checkup for your car—it’s one of the best investments you can make for long-term reliability.
